Is there a "best" 94?

I have wondered if there is a difference in the variations of the 94 carburetor. By that I mean sufficient differences from one model to another to make one actually better than another either in a single carburetor application or multi-carb use. For instance, I have heard for years that the 91-99 is the preferred one to use in mulit-carb applications. If that is so then why is it better than say the Ford version or the Chandler-Grove or the Holley? Can anyone shed any light on this or is this just an old wives tale? :confused: :rolleyes:
 
In my opinion Ford , Holley and Chandler Grove 94's are the same, none better than
other. The styles that came out in '48 truck and '49 pass had the vac port for the
Load a Matic dist, that port can be plugged if not needed. Once the 8ba motor was
introduced various weird throttle arms were featured for various reasons. There are
a few different nozzle bars used , especially in the 8ba and up years, which require a specific air horn for clearance.

As Charlie advises, all the early 94's (CG; 91-99; 21-29; 59) are the same internally, the differences being in how the controls connect up, with one improvement being the internal as opposed to external vent.

59's are the easiest to find and have the good vent. Look carbs over carefully...the big rebuilders back then dumped all the parts from a zillion Ford carbs into a pile, and reassembled at random! MANY are mixes of different castings.
The original carbs were manufactured by Ford and by Holley, all with Ford script as Ford owned the carb. At the bottom of the bulge for the accelerator pump on the right side of the central casting you will learn the original manufacturer...there will be a block letter H for Holley or an F, usually script, for Ford.
Ford allegedly had more sophisticated tooling with better alignment of screw holes and such. There are also light and heavy cast iron bases...I think the light ones are Ford with tighter control of the casting, but that is a sort of statistical guess...there is no sure way to tell if the parts all originated from the same carb 70 years ago!
The commercial rebuilds that mixed up the parts long ago were really dirt cheap, so most people never opened a carb...they swapped it out at Western Auto or whatever for like $3.
 
Also wanted to state that 94 isn't a model number. 94 was the original venturi size that was cast on the carb. It did look basicly the same through 1956 model year on Ford cars, but had revisions along the way. In 1954 it went to 1" venturi, and in '55 and '56 it was a 1 1/16" venturi. The size went up with larger engine displacement.
Also, the 1954 and up models had a spark valve on the throttle body for the Load-O-Matic distributor advance system. Earlier years used Load-O-matic too, but minus the spark valve.
There were also changes along the way that I'm not qualified to say when they were implemented, like discharge nozzle styles and vent hole and tube locations.

Right. The Model number of all the OEM Ford carbs is on the left of bowl, and it is the prefix from the basic part number (9510) for a carburetor. A 59 is a 59A-9510 in the good book. Prewar ones carried both the Ford and Merc designations, as in 21-29.
 
When did those 2110 Holley carbs come into play? They are in the same family as the 94's right?

My only time dealing with one of those was with a Bug Spray set-up on a VW Bug I had in H.S.
 
Yes, they are all similar to what is called the "94".

The breakdown for models and years is:

91-99 '39 - '41
21-29 '42
59 '46 - '48
8BA '49 - '51
2100 '52 - '55
2110 '56 (with auto choke)

Note that those 2100-2110 types still had the Ford model numbers, EAB, ECG something, etc. the 2100 stuff is Holley designation and was used later on with carbs that were purely aftermarket like the Bugspray
 
I think those are entirely a Holley product not connected to Ford, a later replacement part. I think the Bug Spray was fairly large, not really a 94, since barrels were I think isolated in that application and lots of capacity was needed thus.
 
So, have any of you carb guru's figured out the difference between #69 and #71 accel pump shooters??? Just wondering...... Thanks.
 
The but spray I believe all had a four bolt base rather than the "94's" three bolt. I know all the ones I've seen have.
The 2100 was a holley number for a generic replacement carb rather than a specific Ford carb, I believe.
My favourite carb of the "94" family is the late ones with the round boosters, like you find in the Holley 4bbl. They worked so much better that the power valve restriction was shrunk down to 0.025". A nice very responsive carb.

Good point. Yes, my Bug Spray had a 4 bolt. Love those VW motors. Even simpler than a flathead.
